OPINION
On аppeal from a grant of summary judgment, Sol Anker argues the trial court erred by construing Minn.Stat. § 169.685, subd. 4 to apply to crashworthiness actions, and that this application of the statute violates his rights under the Minnesota and United States Constitutions.
FACTS
On December 30, 1993, Sol Anker and his wife were passengers in a rented Ford Tempo. While a friend drove the аutomobile, Anker sat in the right rear passenger’s seat and his wife sat in the front passenger’s seat. Anker’s wife wore an automatic shoulder belt, but had not engaged the manually-operated lap belt. The Tempo collided with a garbage truck that crossed the highway in *336 front of it. As a consequence of the accident, Anker’s wife sustаined fatal injuries.
As trustee for his wife’s heirs, Anker filed a wrongful death negligence action against the Tempo’s driver, the truck driver, the truck driver’s employer, and the rental car company. The truck driver and his employer filed a third-party complaint against Ford Motor Company, alleging its design of the Tempo’s seat belt restraint system rendered the automobile uncrashworthy. Anker subsequently filed an identical complaint against Ford.
Ford moved for summary judgment claiming Minn.Stat. § 169.685, subd. 4 prohibits the introduction of evidence of seat belt use or nonuse in any litigation involving personal injury, thus rendering Anker unable to prove that his wife’s failure to use the lap belt caused her death. The trial cоurt granted Ford’s motion. Later, Anker settled with the remaining parties for $680,000.
ISSUES
I. Does Minn.Stat. § 169.685, subd. 4 apply to crashworthiness actions?
II. Does application of Minn.Stat. § 169.685, subd. 4 to crashworthiness actions violate the Minnesota and United States Constitutions?
ANALYSIS
The interpretation and constitutionality of statutes are questions of law, which we review de novо.
Estate of Jones v. Kvamme,
I.
When interpreting statutes, our function is to ascertain and effectuate the intention of the legislature. Minn.Stat. § 645.16 (1994). If the statute is free from ambiguity, we look only at its plain language.
Id.; Tuma v. Commissioner of Economic Sec.,
Minn.Stat. § 169.685, subd. 4 provides:
Proof of the use or failure to use seat belts or a child passenger restraint system as described in subdivision 5, or proof of the installation or failure of installation of seat belts or a child passenger restraint system as described in subdivision 5 shall not be admissible in evidence in any litigation involving personal injuries or property damage resulting from the use or operation of any motor vehicle.
This language is unambiguous in prohibiting the admission of evidence of the use or non-use of seat belts in
any
litigation involving personal injury that results from the use or operation of а motor vehicle.
Swelbar v. Lahti,
Anker acknowledges the facts of this case fall within a mechanical application of the statute’s broad language. However, he argues the legislature could not hаve intended to prevent injured passengers from bringing crashworthiness suits against manufacturers in cases requiring proof of the nonuse of seat belts. To persuade us to look beyond the statute’s plain language, Anker argues the statute’s location among traffic statutes creates an ambiguity, a literal reading of the statute yields аn absurd result, and the national trend supports his position.
A. Statute’s Location
Anker argues the section’s location among traffic statutes creates an ambiguity regarding the legislature’s intent to destroy the ability to maintain crashworthiness suits that rely on seat belt evidence.
See Bridgestone/Firestone, Inc. v. Glyn-Jones,
B. Statute’s Result
Anker also argues that, by allowing manufacturers to escape liability for designing seat belts that cause injury, the statute’s plain language produces an absurd result, utterly departing from its purpose.
See Glyn-Jones v. Bridgestone/Firestone, Inc.,
In support of his argument, Anker speculates that when the legislature enacted the gag rule in 1963 as part of a measure
*338
requiring manufacturers to install seat belts, it intended nothing more than the protection of plaintiffs from charges of contributory negligence. While we agreе the gag rule typically serves this purpose,

Anker points to no evidence demonstrating a clear legislative intention that the statute not permit manufacturers to make similar use of its unqualified and plain language. One could speculate with equal force that the legislature simultaneously imposed a duty to install novel safety devices and, in exchange, extended a measure of protection to automobile manufacturers; because, well after the bill’s passage, reputable studies continued to suggest that seat belt use could
exacerbate
injuries.
See, e.g., Romankewiz v. Black,
C. National Trend
Anker further argues we should follow the “national trend” of admitting seat belt evidence in crashworthiness actions. However, the bulk of that trend consists of cases recognizing that
common law
principles do not prohibit the introduction of seat belt evidеnce in crashworthiness actions.
See, e.g., Daly v. General Motors Corp.,
Anker cites two cases in which courts have admitted seat belt evidence despite the existence of statutes purporting to bar the introduction of information regarding seat belt use оr nonuse.
See Bridgestone/Firestone,
II.
Anker argues that, if we construe the gag rule to defeat his crashworthiness action, we must declare the statute violative of Minn. Const, art. I, § 8, as well as the Equal Protection and Due Process Clauses of the Minnesota and United States Constitutions. We will uphold a statute unless a party proves it unconstitutional beyond a reasonable doubt.
Kvamme,
A. Minn. Const. Art. I, § 8
Minn. Const, art I, § 8 provides:
Every person is entitled to a certain remedy in the laws for all injuries or wrongs which he may receive to his person, property or character, and to obtain justice freely and without purchase, completely and without denial, promptly and without delay, conformable to the laws.
As Anker acknowledges, article I, section 8 does not guarantee redress for every wrong, but prohibits the legislature from eliminating remedies available at common law unless it does so to further legitimate objectives.
See Hickman,
The gag rule does not violate Minn. Const, art. I, § 8. First, while the crashwor-thiness doctrine is a product of common law negligence, no court recognized the particular duty until 1968, fivе years after passage of the gag rule.
See Hofer v. Mack Trucks, Inc.,
Second, even if a remedy for crashworthiness had vested at common law, wrongful death actions did not vest at common law and аre not protected by Minn. Const, art. I, § 8.
Ackerman v. American Family Mut. Ins. Co.,
And third, even assuming the gag rule abrogated a common law right, Anker has not demonstrated beyond a reasonable doubt that the legislature lacked a legitimate reason for doing so.
See Kvamme,
*340 B. Equal Protection
Anker also argues the gag rule creates an irrational distinction by rendering the crashworthiness doctrine unavailable only tо plaintiffs relying on seat belt evidence.
See Price v. Amdal,
C. Due Process
Anker further argues the gag rule violates his due process right to present evidence.
See Juster Bros. v. Christgau,
DECISION
Anker has demonstrated neither the ambiguity of the gag rule’s language, nor that its effect absurdly and clearly contradicts its purpose. We follow the statute’s literal meaning and hold it applicable to crashwor-thiness actions. This application of the gag rule does not violate Anker’s rights under the Minnesota or United States Constitutions because: (1) Anker has demonstrated neither that it abrogates vested common law rights nor that it lacks a legitimate purpose; (2) Anker has not shown, beyond a reasonable doubt, that the statute serves no rational purpose; and (3) the statutе extinguishes Anker’s cause of action instead of suppressing his presentation of information material to judicial apportionment of liability. The trial court properly granted summary judgment in favor of Ford.
Affirmed.
